Granted: 1997-06-10
Abstract: The present invention provides an improved oil separator in which the oil/refrigerant mixture is caused to flow through two different filter elements. Each of the filter elements is contained in a separate chamber within the separator. A valve assembly is also provided that selectively permits only oil to flow from the first chamber to an oil collection area in the second chamber. The valve assembly regulates the flow of collected oil to the collection area such that the oil/refrigerant mixture cannot escape from the first chamber except by flowing through the filter element of the second chamber. In one embodiment, the valve assembly can include an elongated oil drain extending from a first end adjacent to an oil drain aperture in a dividing wall separating the first and second chambers to a second, open end. A valve seat is formed on the second end of the oil drain. A ball valve element is provided for selective sealing engagement with the valve seat, and the ball valve element is biased toward engagement with the valve seat by a resilient member. In a preferred embodiment, the invention provides a multi-stage device for separating oil from a gas. The device includes a first chamber having an access opening and containing a first filter element. A second chamber is provided adjacent to the first chamber, and contains a second, replaceable filter element. A passage is formed in the first chamber that leads from the second chamber through the access opening in the first chamber, whereby the second, removable filter element can be removed from the second chamber through the access opening via the passage. The second, replaceable filter element may be removed from the separator by means of an elongate handle member having a first end secured to the replaceable filter element; and a second end disposed adjacent to the access opening in the first chamber.

Title: High power ac traction inverter cooling
Inventor: BAILEY RONALD BARRY
IPC: B60L15/00
Filed: 1993-04-22
Granted: 2003-08-05
Abstract: A plurality of high power semiconductor devices (42) are connected in circuit with at least one electric traction motor for controlling electric power to the motor. The semiconductor devices are each thermally connected between a pair of generally hol-low heat sinks (36A, 36B) adapted for passing cooling air therethrough for extracting heat therefrom. M anode terminal of the devices is coupled to one of the heat sinks of a pair and a cathode terminal of the devices is connected to the other heat sink of the pair. Each of the heat sinks are mounted in a cantilever fashion to a common air plenum forming one wall of an electrical circuit area of the vehicle. The distal ends of the heat sinks of a pair are coupled together by an air how conduit (38) thus forming a con-tinuous air passage through the pair of heat sinks which begins and ends at the surface containing the air supply plenum. Cooling air is then directed into the end of the other heat sink, circulating through the one heat sink and out through the exhaust conduit (40). In this manner, the cooling air is held in a closed path extending into the electrical circuit area so that contaminants are not deposited on the electrical components.

Patent CA-2132946-C (CA)
Inventor: GUSTAFSON KEITH W
IPC: F01K25/02
Filed: 1994-09-26
Granted: 2004-12-14
Abstract: A relief valve is provided in the dip tube line that provides a fixed back pressure of 2-3 psi. When the economizer valve on the economizer circuit opens, the back pressure in the dip tube is the head pressure plus the 2-3 psi created by the relief valve. This pressure creates a path of least resistance through the economizer circuit such that the demand of product will draw gas from the gas head via the economizer line until the pressure falls below the valve set at the regulator. Once the pressure falls below the valve set at the regulator, the regulator closes the economizer circuit and liquid will be drawn through the dip tube. Because the relief valve prevents flow back into the tank, an orifice is provided to allow back flow of the cryogen from the withdrawal line to the tank once delivery of product is stopped.

Title: Mobile communications method
Inventor: ITO SHOGO
IPC: H04W68/00
Filed: 1994-10-19
Granted: 2005-10-11
Abstract: In a mobile communications system wherein the transmission form changes in the course of the signal, high quality transmission of change information relating to the transmission form is obtained. To achieve this, information giving advance notice of a change is transmitted prior to transmitting the change information relating to the transmission form.      Even if a situation arises in which transmitted information has not been conveyed without error at a scheduled change time that was notified in advance, it is possible to cope with this situation by referring to the information giving advance notice of the change. This enables faulty paging and other defects resulting from erroneous changes of transmission form to be reduced.

Filed: 1994-01-03
Granted: 1998-05-26
Abstract: This invention relates to a process for preparing selectively hydrogenated polydiene block copolymers with regiospecifically placed epoxy groups. The process involves polymerizing a conjugated diolefin under anionic polymerization conditions to form a living polydiene which is combined with a conjugated diolefin having a degree of substitution  different than the previously  mentioned conjugated diolefin to form a block copolymer which is reacted with hydrogen gas in the presence of a soluble transition metal catalyst and an organometallic reducing agent to form a selectively hydrogenated block copolymer, and epoxidizing the unsaturated sites of the non-hydrogenated blocks. This process allows a variety of structural geometries to be obtained in which the level of functionality is varied independent of molecular weight.

Title: Seed counting apparatus for a planter monitor
Inventor: DRAGNE RASVAN N
IPC: A01C7/10
Filed: 1995-09-22
Granted: 2001-12-11
Abstract: A seed counter for counting seeds flowing through a duct includes a light transmitter on one side of the duct and light receiver on the opposed side of the duct together with an electronic circuit effecting analysis of the signals received by the receiver to generate a seed count value which represents accurately as possible the number of seeds passing through the duct. The transmitter and receiver each comprise a channel-shaped body with diodes at a base of the channel with the channel filled with a translucent potting material facing into the duct. The circuit receives the signals which include for each passage of a seed or a clump of seeds a temporary reduction in light intensity which is converted to a reduction in voltage.  Prior to start up the steady state voltage is measured and the current to the transmitter varied to provide a predetermined level of signal at the receiver.  The circuit includes a DC compression circuit and a AC compression circuit at an amplifier so as to provide an output signal in a required amplitude range. An auto-biasing section maintains a steady state signal at a required level. The amplitude of the signal is compared to a threshold by generating a first signal which is offset by the threshold and a second signal which is delayed by a predetermined time period, the comparison generating a square wave output when one of the signals crosses the other signal. The seed counter is used in a monitoring system having a central monitor which can be operated to vary the parameters of the comparison circuit including the time delay. The use of the comparison circuit assists in determining the difference between a single seed and a clump of seeds passing the transmitter/receiver simultaneously.
